406 HTTP Status Code in REST APIs: A Developer's Guide
In REST APIs, the 406 HTTP status code signals that the server cannot return a response in the format requested by the client. This often relates to the Accept header, which defines what content types the client can process. If none match the server’s capabilities, a 406 is returned. To handle this, ensure your API supports common types like application/json and implements a fallback content-type strategy. Developers should validate header input and log negotiation failures.
